Description

Technical Field

[0002] In various production sites, especially construction sites, safety fences are important facilities to ensure the safety of personnel and divide the work area. At present, the commonly used safety fences are mainly metal frame type, rope net type, retractable cordon and municipal water barrier (fence).

[0003] Metal frame fences are inconvenient to transport because their components are welded and integrated. They have high storage and transportation costs due to their large volume, are not strong enough and are easy to bend and deform, and are limited by the use environment. They are only suitable for flat bottoms and hard cement floors. Rope net fences are prone to knotting when they are retracted and extended, which affects work efficiency. The flexible structure is not durable, has no warning function, requires additional support frames for a long enclosure range, is easy to be contaminated and difficult to clean, is flammable, and is not resistant to strong winds. As a flexible material, the retractable warning line has many disadvantages similar to rope net fences, and cannot be fixed in narrow and limited space workplaces. Municipal water barriers are not only inconvenient to transport, have large volumes, are greatly affected by the environment, and have no warning function, but also have high rental costs, high water consumption during use, and are not environmentally friendly.

[0004] Especially in outdoor power construction, foundation pit excavation and deep foundation pit operations are often involved, and the existing four types of safety fences cannot take into account convenience, safety, environmental adaptability and cost-effectiveness. To this end, the present invention proposes an accordion-type safety guard net structure. Summary of the invention

[0047] It should be noted that the accordion-type safety net structure can be freely retracted and deployed, occupies little space, is easy to transport and use, and can be applied to complex construction environments.

[0048] The above is an embodiment of the present invention provided by the embodiment of the accordion type safety net structure of the first embodiment, the following is an embodiment of the present invention provided by the embodiment of the accordion type safety net structure of the second embodiment, please refer to the specific Figures 1 to 13 .

[0049] The accordion-type safety net structure in this embodiment includes: two supporting bodies 1 and a metal mesh body 2 connected between the two supporting bodies 1; the metal mesh body 2 is composed of a plurality of X-shaped telescopic bending units to form a diamond mesh structure, the X-shaped telescopic bending unit includes a first metal sheet 21 and a second metal sheet 22 symmetrically arranged on both sides of the first metal sheet 21, the intersection of the first metal sheet 21 and the second metal sheet 22 is movably connected through a mesh telescopic bending connector, the end of the first metal sheet 21 of the X-shaped telescopic bending unit is movably connected to the end of the first metal sheet 21 corresponding to the adjacent X-shaped telescopic bending unit through the mesh telescopic bending connector, and the end of the second metal sheet 22 of the X-shaped telescopic bending unit is movably connected to the adjacent X-shaped telescopic bending unit. The end of the second metal sheet 22 corresponding to the telescopic bending unit is movably connected through a mesh telescopic bending connecting piece, and the mesh telescopic bending connecting piece includes a connecting sleeve 23 and a rotating shaft 24. The first metal sheet 21 is fixedly connected to the connecting sleeve 23, and the two ends of the rotating shaft 24 are respectively fixedly connected to the second metal sheets 22 symmetrically and cross-arranged on both sides of the first metal sheet 21; the rotating shaft 24 is passed through the connecting sleeve 23, and there is a movable gap between the rotating shaft 24 and the inner wall of the connecting sleeve 23, so that the rotating shaft 24 can rotate along its own axis, and at the same time can be tilted at various angles relative to the central axis of the connecting sleeve 23 in the connecting sleeve 23, thereby effectively realizing the flexible expansion and contraction and multi-angle bending of the metal mesh 2.

[0050] It is understandable that the accordion-type safety net structure is easy to use and can be assembled and recycled in a relatively short time. Among them, the metal mesh body 2, on the basis of satisfying the telescopic function, also has a certain degree of arc bending function, which can further solve the problem of excessive number of ordinary fences when placed in polygonal form, save materials in construction, reduce costs, and at the same time adapt to a variety of jagged working environments. When enclosing, it can isolate the working area in all directions while meeting the principle of "no duplication and no leakage". In addition, the accordion-type safety net structure also has the advantages of not taking up too much space, easy disassembly and assembly, convenient transfer and transportation, and no hindrance to construction operations.

[0051] The number of the metal mesh bodies 2 can be two, and the two metal mesh bodies 2 are arranged in parallel and spaced apart to form a double-layer structure, and the meshes of the two metal mesh bodies 2 are arranged in a staggered and overlapping manner.

[0052] It should be noted that: by using two metal mesh bodies 2 to form a double-layer laminated mesh, the strength and stability are improved while the protection effect is greatly improved.

[0053] The two ends of the connecting sleeve 23 are trumpet-shaped, which can further increase the tilt angle of the rotating shaft 24 in the connecting sleeve 23, thereby improving the overall bendability of the metal mesh body 2.

[0054] Specifically, the length of the first metal sheet 21 is equal to the length of the second metal sheet 22 , and the intersection of the first metal sheet 21 and the second metal sheet 22 is located at the middle point of the first metal sheet 21 and the second metal sheet 22 .

[0055] The first metal sheet 21 and the second metal sheet 22 can both be made of aluminum alloy, which has certain strength, is sturdy and durable, is lightweight, is not prone to rust and corrosion, and is easy to maintain (after being stained with oil, dust, and mud, it only needs to be rinsed with water to keep it clean).

[0056] The support body 1 is provided with fixing pins 5 for fixing the support body 1 on the ground, which can be applicable to construction sites of various types (hard cement ground, mud ground, depressions, etc.) and landforms (flat ground, sloping ground and uneven ground). By using the fixing pins 5 to fix the support body 1 to the ground, it is not easy to tip over, overturn, sink or be placed unsteadily.

[0057] A universal wheel 4 may be provided at the bottom of the support body 1, and a brake device 8 is provided on the universal wheel 4 to facilitate movement and fixation.

[0058] A handle 3 may be provided on the support body 1 for more convenient use.

[0059] The outer surface of the support body 1 is provided with a reflective warning tape, so that it is easy for operators to notice it during nighttime operations.

[0060] Specifically, the support body 1 is a columnar structure, and the material of the support body 1 is stainless steel, which has high strength, is not easy to bend and deform, and has greater safety and durability.

[0061] A fixing buckle 6 and a fixing position 7 for cooperating with the fixing buckle 6 on an adjacent supporting body 1 are provided on the outer side of the supporting body 1 . The supporting bodies 1 of two adjacent accordion-type safety net structures are fixed together by the fixing buckle 6 and the fixing position 7 .

[0062] During specific implementation, multiple accordion-type safety guard net structures can be transported to the area that needs to be enclosed, and then the accordion-type safety guard net structures can be adaptively stretched and bent according to the shape of the area to be enclosed, and multiple accordion-type safety guard net structures can be connected in sequence to finally achieve arc-shaped enclosure without dead angles.

[0063] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
